pkpass
This tool collects nothing, because there is nothing here to collect it with. It has no server, no database, and no account. Your ticket is read, converted and drawn entirely inside your own browser, and never travels anywhere.
01 — Your tickets
When you drop a .pkpass file onto the page, the browser reads it into memory and the conversion runs there. No copy is uploaded, transmitted, or written to disk except the file you choose to download.
Everything is released when you close or reload the tab. Nothing survives it. There is no history, no queue, and nothing to delete afterwards.
02 — What is stored
Nothing. No cookies, no local storage, no session storage, no fingerprinting, no analytics, no error reporting. The page keeps no state between visits, which is why it forgets your chosen style every time — a small annoyance that comes with storing nothing at all.
03 — What crosses the network
Loading the page fetches its own files: the HTML, one stylesheet, two scripts, and the fonts. That is the entire list. After it has loaded, the page makes no further requests of any kind.
There is no third party involved — no CDN, no analytics service, no tag manager, no embedded widget. The typefaces are served from the same place as the page rather than from a font service, precisely so that opening this page tells nobody else that you did.
04 — Leaving the page
The footer links to the source repository on GitHub. Following it is a normal visit to GitHub and their terms apply there, but only if you click it — nothing is requested from them otherwise.
05 — Whoever hosts this
One honest caveat. These are static files, and any web server that serves a file normally records that it did: your IP address, the time, and which file was asked for. That is between you and whoever is hosting this copy, and it is the same for every website you visit. It happens before any of your ticket data exists in the browser, and it can never include it.
06 — Checking for yourself
You do not have to take any of this on trust. The simplest test: disconnect from the internet, then convert a ticket. It still works. A tool that uploaded your pass could not.
For a closer look, open your browser's developer tools, watch the Network tab while you convert something, and see that nothing goes out. The source is public and can be read line by line.
